Hi list

- thank you for the answer. I actually don't know if I really have such an ATI
card in my IBM Thinkpad R50....Don't know really how to find out...

- I just did another YaST(sax), I selected the one and only IBM
LCD display adaptor that there is to choose. This proved to be very good.
Actually excellent. No distortions, all is just perfect.

- so conclusion: SuSE10.2 somehow suggested a slightly wrong driver and thus
wrote a "not so good" config file for it. Once corrected, SuSE10.2 is
displaywise on an R50 - just excellent.
